or Disjunct Proportion, is when the ratio of two or more pairs of numbers or quanti- ties is the same, but there is not the same proportion between all the four numbers. Thus if the numbers 3 : 6 :: 8 : 16 be considered, the ratio between 3 : 6, is the same as that between 8 : 16, and therefore the num- bers are proportional; but it is only discretely or dis- junctly, for 3 is not to 6 as 6 to 8; that is, the pro- portion is broken off between 8 and 3, and is not con- tinued as in the following continual proportions, 3 : 6 :: 12 : 24.
